Description QingLong 2006-10-17 05:41:24 EDT
Description of problem:
No real network action succeeds in 2.6.18-1.2200.fc5.i686 kernel,
the kernel prints `security_compute_av:  unrecognized class 57'
and the operation fails with `Operation not permitted'.
So I have to run the kernel with selinux=0 to get networking functionality.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Just load the kernel
Actual results:
Networking functionality is effectively disabled.

Expected results:
Networking should be available.

Additional info:
selinux related packages installed on the system:

Exactly the same problems.
selinux enabled
sshd, named, ping, and other network functionality stops working.

It continues to work as a router, but it doesn't connect itself to the network.

Lots of
security_compute_av:  unrecognized class 57
during bootup and shutdown.

I did a /.autorelabel, thinking it was a labelling issue, but same problems.

Everything works again with previous kernel.

I think this is high priority problem.

Could this be a initrd problem?
Comment 3 Dave Jones 2006-10-18 02:47:52 EDT
argh, this stuff should have been disabled.  I've fixed it in CVS. There'll be
an update real soon.  In the meantime, boot with selinux_compat_net=1

I also see the "security_compute_av:  unrecognized class 57" messages on boot up
of one of my machines however this system never finishes booting to see exactly
what is impacted. I tried booting with "selinux_compat_net=1" and SElinux set to
enforcing, no luck. The only way I can get the system to boot is to disable
selinux or boot to the older kernel.
Comment 6 Robert 'Bob' Jensen 2006-10-18 11:35:20 EDT
Oh I am sorry "selinux_compat_net=1" did work, sorry about adding a premature "Me2"
Comment 7 jlbartos 2006-10-18 18:53:48 EDT
selinux_compat_net=1 also works for me
Comment 8 Dave Jones 2006-11-12 00:51:26 EST
should be fixed in 2.6.18-1.2239.fc5 now in updates.
